1 N E W Modular Temperature Controllers Radically Increase the Performance of Multipoint Temperature Control with the EJ1.

2 EJ1 Achieve Optimum Temperature Control for a Device. The EJ1 is a new type of Modular Controller that increases device performance from design and installation through maintenance. Additional functions required for multipoint temperature control have been added to the EJ1 to reduce even further the amount of work required for setup and communications. It enables building systems that meet customer needs. The area for programless communications with PLCs has been expanded to 1,00 parameters. Bit specifications for operation commands reduces the amount of work required for ladder programming. NP-series PT screen templates for the EJ1 reduce the amount of work required to create screens. Reduced Design Work CX-Thermo Support Software supports multi-node settings. A switch can be set to enable monitoring the output status on operation indicators. A switch can be set to use Modbus as the port B communications protocol. Easy Installation and Setup mart C S oncept Independent heating/cooling PID control and autotuning (AT) for heating and cooling. Self-tuning (ST). Control and Adjustment Optimum cycle control with the G3ZA and phase control with the G3PW.

3 Output status monitoring to reduce startup work Screen templates for easier NP-series PT screen creation Twice the number of programless parameters for flexible monitoring and alarms Reliable optimum heater control Multi-node settings for easier multi-channel settings Version Upgrade: The Ultimate in User-friendly Design to Directly Improve Device Performance. Even Better Functions for Multipoint Temperature Control. Modular Temperature Controllers

4 New Functions Incredible User-friendly Design with Advance F Reduced Design Work HFU The capacity of the area for programless communications with PLCs has been increased from 600 (version 1.1) to 1,00 parameters. You can now use more parameters for each loop or to support multipoint control. Programless communications enables exchanging data simply by setting PLC flag operation and the EJ1 parameters. There is no need for creating a communications program. This results in a significant reduction in design work. PLC Memory: DM Area Monitor Settings PV MV Status SP Alarm value 1 Alarm value Data written to the PLC UP Illustration of Connection to OMRON PLC Double the Previous Version Up to 1,00 parameters for each Down Data read from the PLC The HFU automatically performs communications with the PLC. EJ1-HFU Memory: DM Area PV MV Status SP Alarm value 1 Alarm value Note: In addition to OMRON PLCs (SYSMAC CS/CJ/CP Series), you can also use Mitsubishi PLCs (MELSEC-Q/QnA/QnAS/An/AnS/FX3UC Series). However, only some models can be used when multiple HFUs are connected. HFU Operation commands that were previously executed for each channel can now be executed using bit specifications, reducing the amount of work required to create ladder programs. From Set the operation command code for one channel. Set the Operation Command Request Bits. Connectivity and Compatibility Repeat for other channels (ladder program). Programless Communications Operation command To Set the bits for operation commands for more than one channel. (See note.) Set the Operation Command Request Bits. Note: Examples: RUN/STOP, AT Execute/Cancel, Automatic/Manual Screen templates for the EJ1 are a standard feature in the NP-series PTs. There is no need to create basic screens, such as for monitoring the process value, the set point, or the manipulated variable. Examples of Standard Screens - Monitoring the Process Value (PV), Set Point (SP), or Manipulated Variable (MV) - Displaying the status during RUN, STOP, Manual Mode, or AT operation - Displaying the status of the two alarms using lamps - RUN/STOP and AT Execute/Cancel operations for each channel Note: Refer to the NP Series Programmable Terminal (Cat. No. V101) for details.

5 unctionality, Connectivity, and Compatibility Easy Installation and Setup Control and Adjustments CX- Thermo The CX-Thermo Support Software (version 4.1) supports multi-node settings to eliminate the need to change cable connections. It can be easily connected to any EJ1 Controller in a multi-node network. T C Independent heating/cooling PID control (see note) and autotuning (AT) for heating/cooling are provided for devices such as extruders. New Project Window Heating Change nodes from the window. Mold Output Cooling PID for heating PID for cooling Heating output 0 Set Point Cooling output PV Note: This control method allows independently setting PID control for heating and cooling. T C A switch can be set to enable monitoring the output status on the operation indicators. The output status when a device is starting can be checked without using any special software. The communications baud rate settings and protocol changes for Modbus can also be set on a DIP switch. T C Self-tuning (ST) (see note) can be used when AT is difficult to use to control devices with a large heating capacity. Operating Operation Indicator PWR/1 RUN/ ERR/3 ALM/4 Lit green while power is ON. Lit green during operation. Flashes or lights red when an error occurs. Lights red when an alarm occurs. Operation Indicator Monitoring Output Status (New Function) Operation Indicator PWR/1 RUN/ ERR/3 ALM/4 Lit green while OUT1 is ON. Lit green while OUT is ON. Lit red while OUT3 is ON. Lit red while OUT4 is ON. Note: Self-tuning (ST) finds the PID constants by using step response tuning (SRT) when the EJ1 is operating or the set point is changed. ST ST Pin 6 of Switch : OFF Switch Pin 6 of Switch : ON Note: Pin 6 of switch can be turned ON or OFF while the power is ON. Normally keep this pin set to OFF so that operation status can be checked.

7 Applications EJ1 Electric Component Furnaces The EJ1 can control up to 1,04 channels with programless communications. Monitoring of multipoint heater temperatures and integrated processing with high-precision controls are easy for continuous furnaces to create a system without waste. Reduced Work The amount of work required to create ladder programs is reduced by using bit specifications for operation commands. Multivendor Use OMRON or Mitsubishi PLCs Easy CX-Thermo can be easily connected to a multi-node EJ1 network. Wiring is reduced with distributed placement by zone. High Speed High-speed data communications at 115. kbps between Units NS-series PT RS-3C/ Molding Machines Independently set heating/cooling PID control improves control of molding machines. OMRON's unique optimum cycle control improves the power factor and reduces energy consumption. Easy Easy communications with programless communications Large Capacity Reliable programless communications for multipoint operation with data exchange for up to 1,00 parameters. High Speed High-speed communications at 115. kbps even for high-volume data. Independent heating/cooling PID control responds dependably to control characteristics. Easy The PID constants can be calculated by autotuning (AT) for heating/cooling control. Convenient Self-tuning (ST) (see note) can be used to control devices when autotuning (AT) is difficult to use. Note: ST cannot be used for Heating/Cooling Control. Convenient The communications protocol and baud rate can be changed by setting a DIP switch. All parameters can be set with Modbus communications Modbus Reduced Work Optimum cycle control, peak current suppression, and power factor improvement is made possible by direct connection to the G3ZA. Note: Do not use the manipulated variable (MV) calculation for the G3ZA when using self-tuning (ST). Screens can be created in no time using the NP3 screen templates. The above application examples are provided for reference only. Always confirm devices, equipment functions, and safety before using the EJ1 in any specific application. When using the EJ1 in applications requiring special attention to safety, be sure there is sufficient margin in ratings and performance and take suitable safety measures, such as installing failsafe measures. Also, consult with your OMRON representative and confirm specifications and other related documents.
